The following heat times assume you have a fully charged DEWBU battery.

For 12V heated jackets, vests, and pants, the battery will last 3.5–4 hours on high, 5–6 hours on medium, or 9–10 hours on low.

Fully charge the battery before first use. The battery is fully charged when the display reads “100.” Use a compatible USB-C power adapter and follow the instructions included with your battery.

Yes. DEWBU batteries are designed with multiple safety protections for reliable and safe use:

• Global Certifications: Our batteries are CE, FCC, and UL2056 certified, meeting recognized international safety standards for portable power.
• Smart Management (BMS): The built-in battery management system helps protect against over-discharge and overheating. It also activates Sleep Mode during extended periods of inactivity to help preserve battery health.
• Premium Cells: We use high-quality 54Wh lithium-ion cells to provide stable power output and reliable performance.

No. DEWBU batteries are specifically designed for DEWBU heated apparel. For safety and performance reasons, only use the original DEWBU battery.

For optimal battery performance and lifespan, follow these storage recommendations:

• Store the battery with 40%–50% charge in a cool, dry place. The recommended storage temperature is 5°C–10°C (41°F–50°F) and should not fall below 0°C (32°F).
• Avoid storing the battery completely discharged for extended periods. Recharge it every 3–6 months to help maintain battery health.
• When not in use, disconnect and remove the battery from the jacket’s zipper pocket to reduce self-discharge and help extend battery life.

Yes. The USB Type-C port on the DEWBU battery can be used to charge compatible electronic devices, such as smartphones and tablets.

Yes. The DEWBU 54Wh lithium-ion battery may generally be carried in carry-on baggage. Do not place it in checked baggage. Protect the terminals from short circuit and check your airline’s specific requirements before traveling.

No. For safety reasons and to help extend battery lifespan, we do not recommend using the battery while it is connected to a charger.

For continuous warmth, you can connect your heated apparel to a compatible vehicle or 12V power source using the DEWBU 12V connector wire, sold separately.

DEWBU heated gear is designed for both hand washing and machine washing. Follow this standard process to ensure safety and longevity:

1. Remove the Battery: Always disconnect and remove the battery pack from the pocket before cleaning.
2. Secure the Cable: Tuck the power cable back into the battery pocket and zip it completely shut.
3. Wash Carefully: Machine wash with a mesh laundry bag on a gentle cycle using cold water. Do not use bleach or dry clean.
4. Dry Properly: Hang the garment to air dry. Do not wring, twist, iron, or tumble dry, as high heat and mechanical stress may damage the heating elements.

The LED power button on DEWBU® heated apparel uses three colors to indicate different heat levels. You can adjust the setting based on your comfort and surrounding temperature:

• Red (High): Provides maximum warmth, reaching up to 140°F (60°C).
• Blue (Medium): Provides balanced warmth, reaching approximately 125°F (52°C).
• Green (Low): Designed for extended wear, reaching approximately 110°F (43°C).

Operation Tip: Once the battery is connected, briefly press the power button on the garment to cycle through the heat settings.

Yes. DEWBU heated apparel is designed for cold-weather indoor and outdoor activities, including skiing, hiking, tailgating, motorcycle riding, fishing, and more.

Yes, DEWBU heated apparel can still provide warmth in temperatures below freezing.

However, if you plan to spend extended periods outdoors in very cold conditions, we recommend carrying a spare battery to extend your heating time.

No. DEWBU heated apparel is not fire-retardant at the moment. For your safety, always follow the product instructions and use the apparel only as intended.

If your DEWBU battery is not charging your device, it may have entered Sleep Mode after an extended period of inactivity. This feature helps conserve power and extend battery lifespan. To reactivate the battery:

1. Check Battery Status: Press the power button. Flashing LED numbers indicate that the battery is active and working.
2. Disconnect & Reconnect: Disconnect the battery from your garment or device, then reconnect it securely. This reset is the most effective way to reactivate the battery.

Please try the following troubleshooting steps first:

1. Check the battery level: Make sure the battery has sufficient power. If needed, fully charge the battery and try again.

2. Reconnect the battery: If the battery has not been used for an extended period, it may enter Sleep Mode to help conserve power. Disconnect the battery from the garment, then reconnect it securely. Make sure all ports are fully connected.

3. Turn on the heating system: Press and hold the garment power button for about 3 seconds until the light turns on.

4. Test the heating: Set the garment to the red/high setting and wait about 5 minutes to check whether the heating zones become warm.

If the issue persists, please contact our support team with the following information:

• Order Number:
• Order Date:
• Photos or a short video showing the issue (recommended)

Battery runtime depends on your heat setting, environment, and battery condition:

Heat Settings: Using the High (Red) setting provides maximum warmth but uses more power, lasting approximately 3.5–4 hours, while the Low (Green) setting can last up to 10 hours.

External Charging: Charging smartphones or other devices through the USB port will reduce the available heating time.

Cold Temperatures: Extremely cold conditions can naturally affect lithium-ion battery performance.

Battery Aging: As batteries age, their internal capacity gradually decreases, which may result in shorter runtime.

If your battery drains unusually quickly after considering these factors, it may indicate a technical issue. If your battery is still within the 18-month warranty period, please contact our customer service team for assistance.
